Value Collection MS51958-82 Pan Head Machine Screw

Product Description

The VALUE COLLECTION MS51958-82 is a 1/4-28 unified fine thread pan head machine screw with a Phillips drive, manufactured to MS51958 military fastener standard. Built from 18-8 stainless steel with a black oxide finish, this screw measures 7/8 inches in length under head and is sized for applications requiring corrosion-resistant fastening with a low-profile pan head geometry. The Phillips recess allows for installation with standard hand or power drivers. At 0.016 pounds per unit, this is a lightweight fastener suited for precision mechanical assemblies where thread integrity and finish durability matter.

This fastener is used in general mechanical, electrical panel, and light structural assemblies where fine-thread engagement and stainless steel corrosion resistance are required. The 1/4-28 thread pitch provides tighter thread engagement than coarse-thread equivalents, making it a common choice in instrumentation, enclosures, and equipment panels. Installation is performed by maintenance technicians, electricians, and mechanical assemblers across industrial, commercial, and trade service environments. Sold individually per package with a minimum order quantity of 100 units.

Key Features

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies requiring a 1/4-28 fine thread pan head Phillips machine screw per the MS51958 military fastener standard.

Installation Notes

Installation requires a Phillips screwdriver or Phillips-tip power driver sized for a 1/4-inch fastener head. Ensure the mating thread is clean and free of debris before driving to avoid cross-threading, particularly with fine-thread fasteners. Power down or de-energize any electrical panel or equipment before installing or removing fasteners in live assemblies. Do not exceed recommended torque for the mating material to avoid thread stripping in thin or soft substrates.
